+### 文件解密算法
+
+首先以`mcid`（对应漫画id）以及`epid`（对应单话）生成一个 8 Byte 的数组作为密钥
+
+具体内容为前 4 Byte 为 epid 后 4 Byte 为 mcid，字节排序均为小端序 MSB First
+
+接下来从返回数据的 09H 处开始，逐字节与密钥取单个字节进行 **XOR（异或）**运算，密钥数组每 8 Byte 循环一次
+
+解密成功的数据是一个 zip 格式的压缩文件，提取`index.dat`中的数据并以 JSON 数据解析就完成了
+
+### 进行解密操作
+
+设`mcid=26731` `epid=329893`，计算得到的数组便是密钥
+
+```python
+mcid = 26731
+epid = 329893
+key = list(epid.to_bytes(4, 'little') + mcid.to_bytes(4, 'little'))
+print(key)
+```
+
+```python
+[165, 8, 5, 0, 107, 104, 0, 0]
+```
+
+拉取索引数据并解密，需要**跳过前 9 Byte**，这时候已经能看到数据具有 zip 格式压缩文件的特征，前两 Byte 为 “PK”（50H 4BH）
+
+```python
+import requests
+
+data = requests.get('https://manga.hdslb.com/bfs/manga/26731/329893/data.index?token=0ba7042d3a5d138c59151316a1914058&ts=634e53fb').content
+
+temp = bytearray(data[9:])
+for i in range(len(temp)):
+   temp[i] ^= key[i % 8]
+print(temp)
+```
+
+```python
